I'd be more inclined to say "back from the edge". The "ledge", when used that way, often hints at suicide or self-inflicted damage. It comes from the idea (often portrayed in movies) that someone is standing on the window ledge, considering jumping, and another person pulls them back or talks them out of it. If the stocks were on the edge (of ruin, collapse) you might have to pull the CEO back from the ledge. Edge and ledge are similar enough in meaning that they both work, but they are also similar enough in sound that someone familiar with the suicide angle might question what you really intend to convey.
